How do I make sure I choose only non-incentivized traffic?

The Appnext platform does not allow any incentivized traffic.

Any app campaign started with Appnext will be served exclusively on non-incentivized mobile sources.

It is against our policies to encourage or reward the user for installing the app; we only allow rewards as a means of encouraging users to watch the video ad, so they will voluntarily install the app if they are interested.
